oilcloth

thumb|Traditional oilcloth thumb|Rolls of oilcloth Oilcloth, also known as enameled cloth or American cloth, is close-woven cotton duck or linen cloth with a coating of boiled linseed oil to make it waterproof.

== Manufacture == Boiled linseed oil was prepared by a long boiling of linseed oil with metal salts, originally lead dross. The modern oil is less toxic, but also less suitable for making oilcloth. Re-enactors may boil their own oil in the search for a correctly coloured oilcloth. Oilcloth used for weatherproofing may have used a mixture of lead and manganese salts, the sienna and umber pigments, to give a more humidity-resistant cure.
